my 3.3 plugin doesn't work in 3.4 [message #335054]

A plugin I wrote under Eclipse 3.3 does not work in 3.4 - it looks like the
plugin is not activated. I did update MANIFEST.MF to include the following:

Bundle-ActivationPolicy: lazy

But it doesn't work whether the old or new line is present. My plugin
overrides editor hover behavior. I specify the extension point
org.eclipse.jdt.ui.javaEditorTextHovers in plugin.xml. That looks like
this:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>

<extension point="org.eclipse.jdt.ui.javaEditorTextHovers">
<hover
id="myEditorHover"
class="sonif.myEditorHover"
label="lewisCustomHover"
description="A custom hover handler."
activate="true" >
</hover>
</extension>

</plugin>

Any ideas why my plugin is not activated?

No idea. Try with 3.5 M6 and if it is not working there file a bug
report and attach your plug-in.

It is possible that my plugin is not activated because certain code has been
deprecated. I could at least test to see if it's activation works on
demand. Does Eclipse accept any activation policy other than lazy? If so,
what do I substitute for "lazy" in:

Bundle-ActivationPolicy: lazy

?

Hi Lewis,
You can easily check if your plug-in is activated by setting a printout
in the "start()" method in your plug-in "Activator.java" class. If your
message appears in the console, your plug-in is started. Your problem
could be related to deprecated code, or perhaps a deprecated extension
point...
If the activation is not lazy, the "Bundle-ActivationPolicy: lazy" line
in your Manifest.MF is deleted.
